Why You'll Love It
Dealing with tough wastewater challenges requires a pump that doesn't just push water - it needs to handle solids without getting stuck. The Davey Grinder Pump is built to do the dirty work. It features a heavy-duty shredding and grinding ring that shreds soft solids, sanitary products, and even thin rubber into a fine slurry. This means you can pump waste through smaller pipes without blockages. Whether you are connecting to a pressure sewer main or emptying a septic tank, this pump runs quietly and gets the job done reliably.

The Problem Solver
- Shreds Waste Instantly: The heavy-duty shredder ring at the inlet grinds soft organic solids and sanitary items into a slurry, preventing clogs.
- Built Tough: Made with corrosion-resistant 304 stainless steel and powder-coated cast iron parts for long-lasting durability.
- Motor Protection: A double mechanical shaft seal in an oil bath, plus a sand slinger lip seal, keeps grit and water out of the motor.
- Prevents Overheating: The motor has an automatic resetting thermal overload that shuts it down if it gets too hot or draws too much current.
